I have Galaxy 7600GS 256MB DDR3. 500/1000 at default clocks. I didn&t overclock this card but overclocked my 930D. I experience random computer lockup when playing videos with Media Player classic from K-Lite Codec Pack. I also experience random display corruption when starting games. This happens randomly. My processor is stable with 2 Prime so I dont think any problems with processor. PCI express speed set to Auto. I tried running 3D Mark loop but ended up getting error message like Display lost focus. Im using widescreen 1440x900. 7600GS temp ranges from 58C idle and 72C load. Is there any hardware problems with my 7600GS. Or is it software? Im using Forceware 91.33.
